2 SHEETS-SHEET 2- preferred form is for the formation therefrom ofUNITED STATES Application filed January To all whom it may concern.

Be it known that I, JAMES A. GRAY, a citizen of the United States,residing at the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inMultiple-Disk-Cutting Apparatus, of which the following is aspecification.

The hereinafter described invention relates to an'apparatus for themultiple cutting of gasket disks from fiat liner material gasket ringliners for use in connection with lining of can ends employed in thehermetic sealing of cans or metallic vessels containing food products,the object of the invention being the production of an efiicient,economic and rapidly operating. apparatus for simultaneously cuttingfrom a traveling web of liner material a plurality of disks, thedisposition of the cutting mechanism relative to. the traveling webbeing such that the disks are cut or severed from the web with the leastpossible waste of liner material and in its preferred embodiment theapparatus employed operates on two continuously traveling superposedwebs of liner material, whereby on each reciprocating strokeof thecutting punches of the apparatus there is not only removed or cut aplurality of disks from a traveling web of liner material, but equallyso a plurality of disks from a plurality of superposed traveling webs ofliner material.

The purpose of the present apparatus is the severing or cutting from aweb of liner material disks from which ring liners are subsequentlysevered by separate or independent mechanism, which cut ring liners arefor use in connection with the lining of can ends for sealming tocanbodies or metallic containers.

In order to comprehend the invention reference should be had to theaccompanying sheet of drawings, wherein an apparatus of illustrated anddescribed.

of the apparatus, the said frame being provided with a rear or back wallmember2 in front of which the webs of liner material are adapted to passor travel as moved through the machine, the said frame and its backing 2being in the present case vertically disposed. To the frame 1 and inadvance of the backing plate 2 is secured in the present case anobliquely disposed support 3 which is detachably held to the frame 1 andspaced from the backing plate 2 by means of the bolts 4, which secure orunite the bracket extension 5 of the said support 3 to the framestructure 1. The obliquely disposed supporting plate or member 3 isprovided with a series of guide-ways 6 formed by the angle plates 7secured to the said outer face of the said support 3 and within whichsaid guide-ways are mounted for reciprocating movement a plurality ofslides 8, Figs. 1, 3 and 6 of the drawings. Each reciprocating slide 8is united to a driven shaft 9 by means of the pivotallyconnected rod 10which rods in turn are connected to the crank heads 11 secured atintervals to the said shaft 9. At its inner end each of thereciprocating slides has secured or united thereto in any suitablemanner a punch 12, Fig. 6 of the drawings. The crank shaft 9 is drivenfrom a power shaft 13, through the medium of a pinion 15' mountedthereon meshing with the gear 16, secured to'the upper extremity of thesaid crank shaft 9, Figs. 1 and 2 of the drawings,

the drive shaft 13 being driven from any.

suitable outside source of power by means of a power belt, not shown,working over the belt pulley 14 secured to one end of the said driveshaft. On the drive shaft 13 is mounted a worm pinion 16, Fig. 4 of thedrawings, which meshe with a worm 17 secured to a transverse siaft 18mounted in suitable bearings in the frame 1 and situated in a planeabove and at substantially right angles to that of the drive shaft 13.At one end the shaft 18 carries a belt pulley 19, over which works abelt 20 adapted to drive a belt pulley 21 secured to a transverse shaft22 working in bearings at the lower end of the frame 1. The said shaft18 has secured thereto a roll 23 intermediate of its bearings and at itsend opposite to that carrying the belt pulley 19 is secured a pin ion24, which pinion meshes with a similarpinion 25 secured to one end of atransverse shaft 26'arranged in advance of the roll 23 and parallel withthe shaft 18. To the shaft 26 is secured a feedingroll 27, Fig. 2 of thedrawings.

In the present case the apparatus is illus trated as adapted for thecarrying or moving of two superposed webs of paper therethrough, therolls 28 and 29 of liner material being mounted or supported in asuitable holder 30 arranged a distance at the move over the idler rolls32 of the support 31,.the free ends thereof extending downwardly betweenthe feed rolls 23 and 27 and beneath the delivery roll 33, whichmaintains a tension thereon and directs or delivers the same onto thelongitudinall disposed upwardly inclined endless trave ing apron 3 1,the said superposed webs of liner material during their downward courseof travel passing between the alined reciprocating punches 12 and thehollow fixed cutting dies 12, Figs. 1, 5 and 6 of the drawings. There isa cutting die 12 for each reciprocating punch 12, each cutting die beingarranged in horizontal alinement with its associated punch 12. Thesedies 12 are secured within longitudinally disposed spaced openings 35 ofthe fixed backing plate 2 of the apparatus, and project a distance inadvance thereof. As the webs of liner material travel between thepunches 12 and the cutting dies 12 the said punches 12 coact with thedies 12 on the inwardly .reciprocating stroke of the slides 8 to cut outor sever from the webs of liner material a plurality of core pieces36,-which core pieces are gradually forced through the hollow dies 12and the circular openings 35 of the fixed backing plate 2 and move ontothe holder or magazine 37, which holders or magazines in the presentcase consist of a plurality of spaced outwardly projecting rods orsupports 37, Figs. 1, 5, 6 and 7 of the drawings. It will thus be seenthan on each inwardly reciprocating stroke of the slides 8, there is cutthrough the medium of the punches 12 and the dies 12 a plurality of diskblanks or core-pieces 36, which cut disks are delivered onto themagazine or holder 37 until a given number has accumulated thereon,which are then removed for action thereon of independent mechanism forthe cutting therefrom a gasket ring liner of a diameter suitable to fitthe flange of a can end. The disk blanks as cut from the webs of linermaterial move onto the support or holder 37 against a movable frictionblock 37 which maintains the disk blanks in vertical position, it beingunderstood that the said block 37 gives outwardly to the pressure of thecore-pieces thereagainst.

The superposed webs of liner material are 'momentarily arresting of thedownward travel of the webs below the cutting punches, hence a slightbuckling of the webs between the feed rolls and the punches, Fig. 5 ofthe drawings, which buckling is disposed of by the weight of thetraveling webs when freed on the outward or return reciprocating strokeof the cutting punches to release the said webs. It is by reason of thismomentary buckling of the webs which is provided for, that'permits ofthe continuous feed of the webs of liner material. The transverselydisposed roll 33 acting on the webs at the lower portion of the machineserves to maintain or hold the webs under tension and to guide anddirect the free ends of the traveling webs onto the endless travelingconveyer or apron 3a, which apron or conveyer travels over the rollers38 and 38', the roll 38 being driven by the belt 20, which belt is sorun as to train over the belt rolls 19, 21, 21 and 21*, Figs. 1, 2 and 4of the drawings.

While the reciprocating slides carrying the punches 12 have beenillustrated as extending obliquely to the path of travel of thesuperposed webs of liner material, it is apparent that such anarrangement is not essential, inasmuch as the said punches may 1 bedisposed transversely to the path of travel of said webs of linermaterial. However, by arranging the support 3 obliquely I am enabled tocut on a single stroke from a web of given width a greater number ofdisk blanks than could be cut from the same Width of web of linermaterial when the cutting punchesare disposed transversely to the lineof travel of the said webs, and it is for the purpose of securing thecutting of the greatest possible number of disks on a single action ofthe cutting punches that the punches are arranged in a line obliquely tothat of the path of travel of the webs of liner material. In the presentcase, the construction of the apparatus is such that the superposed websof liner material move in a vertical path and the .reciprocating punchesin a path of movement at substantially right angles thereto, but it isobvious that by throwing the frame structure from a vertical to ahorizontal position the line of travel of the webs of liner materialwould be longitudinal instead of vertical, and in such case thedisposition of the series of cutting punches would be relativelyvertical in relation to the width of the-superposed longitudinallytraveling webs of liner material.

The disposition of the reciprocating cut ting punches is such relativeto the travel of the webs of liner material as to permit of the cuttingof the disk blanks in staggered relation, thereby causing the leastpossible waste of liner'material and reducing the cost incident to theproduction of the disk blanks to a minimum, which is an essentialfeature in connection with the supplying of can ends lined with gasketscut from disks of liner material.

While I have illustrated and described the apparatus in its preferredembodiment of interconnected associated working instrumentalities, it isapparent that changes may be made in the detailed construction of theworking parts without departing from the nature and scope of theinvention and I do not wish to be understood as limiting or restrictingthe invention to such described details of construction, but on thecontrary wish to be understood as claiming broadly for the inventioninterconnected or associated working instrumentalities for cutting on asingle reciprocating stroke a plurality of disk blanks from linermaterial either during a continuous or intermittent movement of the websand this irrespective as to whether the cutting mechanism acts relativeto a plurality of superposed webs of liner material or merely on asingle web of liner material.
